Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of cold chain transportation, and specifically relates to a cold chain distribution box with a positioning structure. Background Art
[0002] With the continuous improvement of people's living standards and the increasingly strict requirements for food quality, the cold chain logistics industry has developed rapidly. In modern society, people's demand for temperature-sensitive items such as fresh food and drugs is increasing continuously. These items need to maintain a specific temperature range during transportation to ensure their quality and safety. For example, fresh fruits and vegetables need to be transported in a low-temperature environment to extend their shelf life; drugs need to be transported under strict temperature control to ensure their efficacy.
[0003] Chinese Patent No. CN220577867U discloses a cold chain distribution box with a positioning structure. Through the setting of a connecting positioning structure and a limiting structure, the cooling boxes adjacent to each other on the side and up and down are mutually limited and fixed, preventing the cold chain distribution boxes from colliding with each other when the transport vehicle brakes and accelerates during road transportation, thereby protecting the cold chain distribution boxes and extending their service life. However, during transportation, if strong vibration or impact is encountered, the connecting parts such as positioning columns, insertion blocks, and slots may become loose, thereby reducing the connection stability. For example, when driving on a road with poor road conditions, the bumps of the refrigerated truck may cause the positioning columns to come out of the jacks and the insertion blocks to slide out of the slots, resulting in the failure of the connection between adjacent cold chain boxes and increasing the risk of box collision.
[0004] In view of this, the present utility model is specifically proposed. Content of the Utility Model
[0005] The technical problem to be solved by the present utility model is to overcome the deficiencies of the prior art and provide a cold chain distribution box with a positioning structure, solving the problems raised in the above background art.
[0006] To solve the above technical problems, the basic concept of the technical solution adopted by the present utility model is:
[0007] A cold chain distribution box with a positioning structure includes: a box body, a guiding groove is opened at the top end of the box body, a slider corresponding to the guiding groove is connected to the bottom end of the box body, a fixing block is connected to the top end of the side wall of the box body, a limiting hole is opened on the surface of the fixing block, a fixing mechanism is connected to the bottom end of the side wall of the box body, the fixing mechanism includes a connecting block connected to the bottom end of the side wall of the box body, a connecting column is connected to the bottom end of the connecting block, a rotating block and a limiting block are respectively connected to the top end and the bottom end of the connecting column, a screw rod penetrates through the surface of the rotating block, a sliding groove is opened on the surface of the connecting block, and a bottom plate for placing the box body is further included.
[0008] Optionally, guiding grooves identical to the top end of the box body are provided on the surface of the bottom plate, and limiting holes identical to the surface of the fixing block are also provided.
[0009] Optionally, the box body is of a multi-layer structure, including an outer layer, a heat-insulating layer and an inner layer, and heat-insulating materials are filled in the heat-insulating layer.
[0010] Optionally, the connecting block is in an "L" shape. The longitudinal plate of the connecting block is fixedly connected to the side wall of the box body, and the connecting column penetrates through the transverse plate of the connecting block.
[0011] Optionally, the sliding groove is provided on the surface of the transverse plate of the connecting block. The sliding groove is in a semi-circular arc shape, and a threaded hole corresponding to the screw is provided at the rear end of the sliding groove.
[0012] Optionally, a groove corresponding to the limiting block is provided at the bottom end of the transverse plate of the connecting block.

Detailed Description of the Specific Embodiment
[0030] Now, the present utility model will be further described in detail with reference to the attached drawings.
[0031] Please refer to Figures 1-6 As shown, in this embodiment, a cold chain distribution box with a positioning structure is provided, including: a box body 1, a guide groove 5 is opened at the top end of the box body 1, a slide block 4 corresponding to the guide groove 5 is connected to the bottom end of the box body 1, a fixing block 2 is connected to the top end of the side wall of the box body 1, a limit hole 7 is opened on the surface of the fixing block 2, a fixing mechanism is connected to the bottom end of the side wall of the box body 1, the fixing mechanism includes a connecting block 3 connected to the bottom end of the side wall of the box body 1, a connecting column 12 is connected to the bottom end of the connecting block 3, a rotating block 11 and a limit block 13 are respectively connected to the top end and the bottom end of the connecting column 12, a screw 15 penetrates through the surface of the rotating block 11, a chute 14 is opened on the surface of the connecting block 3, and a bottom plate 6 for placing the box body 1 is further included.
[0032] The guiding groove 5 at the top end of the box body 1 and the sliding block 4 at the bottom end of the box body 1 cooperate with each other. When multiple box bodies 1 are stacked, they play a guiding role to ensure that the box bodies 1 can be accurately stacked up and down, avoid dislocation, and improve the stability of stacking. When multiple box bodies 1 are stacked, the fixing block 2 located at the top end of the side wall of the box body 1, the limiting holes 7 opened thereon, and the fixing mechanism can be used to limit and fix them. The bottom plate 6 is the basic platform for placing the box body 1 and can provide stable support for the box body 1.
[0033] In this embodiment, the guiding groove 5 identical to the top end of the box body 1 is opened on the surface of the bottom plate 6, and at the same time, the limiting hole 7 identical to the surface of the fixing block 2 is opened. This enables the bottom plate 6 to accurately dock with the upper box body 1 like another box body 1 when multiple box bodies 1 are stacked on the bottom plate 6. The guiding groove 5 ensures the accurate placement position of the box body 1 on the bottom plate 6, prevents the box body 1 from sliding or shifting on the bottom plate 6, and improves the overall stability. When the box body 1 is placed on the bottom plate 6, the fixing mechanism at the bottom of the box body 1 can cooperate with the limiting hole 7 on the bottom plate 6 to fix the box body 1 on the surface of the bottom plate 6.
[0034] The box body 1 is a multi-layer structure, including an outer layer 8, a heat insulation layer 10, and an inner layer 9. The heat insulation layer 10 is filled with heat insulation materials. The outer layer 8 has certain strength and wear resistance and can protect the internal structure of the box body 1 from being damaged by the external environment. The heat insulation layer 10 can effectively prevent the heat exchange between the inside and outside of the box, ensure that the items in the box are transported and stored in a suitable temperature environment, and at the same time, the multi-layer structure can increase the thermal resistance and improve the heat insulation performance.
[0035] The connecting block 3 is in an "L" shape. The longitudinal plate of the connecting block 3 is fixedly connected to the side wall of the box body 1. The connecting column 12 penetrates through the transverse plate of the connecting block 3. A groove 16 corresponding to the limiting block 13 is opened at the bottom end of the transverse plate of the connecting block 3. The connecting column 12 can move up and down on the surface of the transverse plate of the connecting block 3. When the box body 1 needs to be fixed, the limiting block 13 can be moved into the groove 16. At this time, the limiting block 13 and the bottom of the box body 1 are in a flat state, preventing the limiting block 13 from affecting the movement of the box body 1 in the guiding groove 5. When the box body 1 moves to the limiting hole 7, the connecting column 12 drives the limiting block 13 to fall into the limiting hole 7, achieving a preliminary fixing effect on the box body 1.
[0036] The sliding groove 14 is formed on the surface of the transverse plate of the connecting block 3. The sliding groove 14 is semi-circular in shape, and a threaded hole corresponding to the screw 15 is opened at the rear end of the sliding groove 14. The surface of the limiting block 13 is semi-circular. The top end of the limiting hole 7 is the same as that of the connecting column 12 and the limiting block 13, and its bottom end is a circular groove with the same diameter as the limiting block 13. When the limiting block 13 drops into the limiting hole 7, rotate the rotating block 11 to drive the connecting column 12 to rotate, so that the limiting block 13 rotates 180° in the circular groove at the bottom end of the limiting hole 7, realizing the fixing effect on the box body 1. While the rotating block 11 is rotating, the screw 15 also rotates along the sliding groove 14, so that the screw 15 rotates into the threaded hole opened in the sliding groove 14, ensuring that the limiting block 13 can rotate 180°. Finally, rotate the screw 15 into the threaded hole, thereby ensuring the fixation of the rotating block 11 and preventing loosening due to jolting during transportation.
[0037] Working principle:
[0038] The multi-layer structure of the box body 1 includes an outer layer 8, a heat-insulating layer 10 and an inner layer 9. The outer layer 8 has certain strength and wear resistance, protecting the internal structure of the box body 1 from being damaged by the external environment. The heat-insulating layer 10 is filled with heat-insulating materials, which can effectively prevent the heat exchange between the inside and outside of the box, ensuring that the items inside the box are transported and stored in a suitable temperature environment. The multi-layer structure increases the thermal resistance and further improves the heat-insulating performance.
[0039] When stacking and fixing the box body 1, move the limiting block 13 into the groove 16. At this time, the limiting block 13 and the bottom of the box body 1 are in a flat state, preventing the limiting block 13 from affecting the movement of the box body 1 in the guiding groove 5. Then, move the slider 4 at the bottom end of the box body 1 along the guiding groove 5, so that the box body 1 moves to the position of the limiting hole 7. At this time, the connecting column 12 drives the limiting block 13 to drop into the limiting hole 7, playing a preliminary fixing effect on the box body 1. Then, rotate the rotating block 11 to drive the connecting column 12 to rotate, so that the limiting block 13 rotates 180° in the circular groove at the bottom end of the limiting hole 7, realizing the further fixing of the box body 1. While the rotating block 11 is rotating, the screw 15 also rotates along the sliding groove 14. When the limiting block 13 rotates in place, rotate the screw 15 into the threaded hole opened at the rear end of the sliding groove 14, ensuring that the limiting block 13 can be stably maintained in the position of rotating 180°. Finally, rotate the screw 15 into the threaded hole, thereby ensuring the fixation of the rotating block 11 and preventing loosening due to jolting during transportation. In this way, the entire cold chain distribution box can stably transport and store items in a stacked and fixed state, ensuring the safe protection of the items in a suitable temperature environment.
